Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As Fig. 1, it is structural representation of the present invention, it is a kind of intaglio printing waste gas afterheat recovery system device, comprise gas recovery system and new wind heating system, gas recovery system comprises the waste gas heat exchange tube road 1, exhaust blower 2 and the exhaust duct 3 that connect successively, installs and purify heat exchanger components group on waste gas heat exchange tube road 1; New wind heating system comprises the new air heat-exchange pipeline 4 with two new wind entrances, and heat exchange of heat pipe 5 and baking oven air intake air intake device 6 are installed on new air heat-exchange pipeline.One end of waste gas heat exchange tube road head has printing process gas inlet means 7, and as can be seen from the figure, printing process gas inlet means is printing machine unit baking oven exhaust outlet.Baking oven air intake air intake device 6 is also printing machine unit heater air inlet.Printing process gas inlet means is to absorb the waste gas producing in printing process.
Purify heat exchanger components group and comprise the purification filtering equipment and the heat exchange of heat pipe 5 that connect successively along exhaust gas flow direction.Purification filtering equipment comprises the photocatalyst or active carbon filtering device 8, main air purifier 10, secondary air purifier 11 and the three grades of air cleaning units 12 that connect successively.Effectively protect heat exchange of heat pipe.
Two new wind entrances of new air heat-exchange pipeline 4 are respectively main air intake vent 42 and time air intake vent 41, and as shown in the figure, with the flow direction main air intake vent 42 by contrast of waste gas in described waste gas heat exchange tube road, another one is time air intake vent 41.Main air intake vent and time air intake vent are all provided with frequency conversion axial flow fan 13, in order to increase the pressure of new wind air intake vent, and can, by frequency conversion, control at any time intake.Inferior air intake vent inside also has steam-condensation water-to-water heat exchanger 14.In the present invention, heat exchange of heat pipe is copper pipe, and the fin of heat exchange of heat pipe is hydrophilic aluminium foil.
Workflow of the present invention is: the high-temp waste gas that printing equipment produces is in process of production from printing each baking oven discharge, import in air draft main pipeline, enter printing waste gas heat exchange tube road, circulate along pipeline, purify by photocatalyst or active carbon filtering device, main air purifier, secondary air purifier and three grades of air cleaning units successively simultaneously, after finishing dealing with, enter heat exchange of heat pipe and heat, heat is delivered to the fresh air in low-temperature condition through superheater tube simultaneously; And remaining waste gas is passed through outside exhaust duct discharge chamber by exhaust blower.Because the new wind of main air intake vent is preheated, enter the heater of unit along new air heat-exchange pipeline, at inferior air intake vent, heat exchanger carries out preheating with the steam condensate (SC) in the printing process of collecting to the air of inferior air intake vent, uses together with the new wind entering with inferior air intake vent and enters new air heat-exchange pipeline.In order to guarantee the quality of new wind, be also provided with filter at the upstream end of main air intake vent and time air intake vent, guarantee that new wind has good quality, the dust in filtered air, avoids heat exchanger blocked.Like this, from main air intake vent and time air intake vent enter and the steam that heats by the sucking-off of baking oven air intake air intake device, complete heat recovery, the waste heat in waste gas reenters print system utilized.
In order to reach utilization rate and the temperature of good control waste gas, in new air heat-exchange pipeline, sensor is set, sensor measurement total pipeline inside and outside differential pressure value, and using this pressure difference as the signal regulating, thereby the rotating speed of regulation and control frequency conversion axial flow fan, carries to reach the air quantity matching with the demand of printing unit.
Exhaust fan adopts speed govornor by frequency modulator, and it is upper that blast differential pressure pickup is arranged on the house steward of exhaust duct, and it is by detecting the blast pressure difference inside and outside airduct and removing automatically to control the rotating speed of exhaust fan according to the size of this pressure difference, thereby controls exhaust air rate.Make exhaust air rate can be in the scope of 30%～100% total blast volume the exhaust air rate of tracking and matching press oven automatically, make baking oven reach required temperature value and best negative pressure value.
